Your Cummings will handle the taller gears better than my Chevy.

Wrap the exhaust and add a turbocharger blanket. Theas allow the turbo to see more waste heat instead of the under side of your hood. A turbocharger turns waste heat into boost. The wrap droped my spoll from 600pegt to 500egt to git 1psi.
